The Record of Strange Dreams in the Southern Song Dynasty

Do you think time travel means time travel really? I am seriously ill with my own system, and the so-called system is myself. I thought I could find my way home, but then I discovered that I am a person of this era, but why do my thoughts not belong to this era? Which one is the real me? I can't go back. I heard that there is a small island not far away called the Japanese Kingdom, so I will try my best to destroy it. This novel and its characters are purely fictitious.
